Nine states have marijuana measures on the ballot this November, and chances are good that many will pass — giving pot advocates high hopes that the federal government will eventually lift its nationwide ban, NBC News reported.

In five states — Arizona, California, Maine, Massachusetts and Nevada — voters will decide on legalizing the recreational use of marijuana.

In four others — Arkansas, Florida, Montana and North Dakota — voters will weigh in on medical marijuana, which is already legal in nearly half the country.
